MOLDERS FLASK.

Specification of Letters Patent.

Patented Aug. 25, 1914:-

To all whom it may concern:

Be itknown that I, WILLIAM SEIDEL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use ful Improvements in Molders Flasks, of which the following is a specification.

The present invention relates to a combined molders flask and match board used in casting operations.

The objects of the present invention are to provide means for centering the cope section and drag section of the flask with respect to the match board, and to provide centering means which will enable an independent centering of either the cope or drag section with respect to the match board as well as a centering of both of said sections with respect to the board.

further object of the invention is to provide means for giving a uniform and even initial lifting movement to the cope and drag sections when it is desired to remove the same from the match board.

A. further object of the invention is to attach metal strips to the match board in a manner to prevent a warping or breaking of the same.

A further object of the invention is to provide a metallic member along the outer edges of the match board which is config ured to permit a dovetailing of the edges of the match board with said strip, thus reinforcing the said edges.

The invention further consists in the features of construction and combinations of parts hereinafter described and claimed.

In the drawings: Figure 1 is an end elevation of the flask of the present invention; Fig. 2 is an enlarged plan view of one end of the said flask; Fig. 3 is a vertical section through one end of the flask; Fig. i is a sec tion on line 44 of Fig. 6 showing the centering members carried by the cope section and the centering members carried by the drag section; Fig. 5 is a section on line 55 of Fig. 6 showing the centering member for the drag section only, and showing how the drag section may be centered independently of the cope section; Fig. 6 is an enlarged vertical sectional detail of one end of the flask; and Fig. 7 is a plan View of the entire flask with the initial lifting members and the centering members removed.

In the operation of molding where a two piece pattern is used, one piece of the pattern can be secured upon one side of the match board and the other piece upon the opposite side and alined therewith. The cope sections and drag sections are then inserted in position above and below the match board respectively and are filled with sand and tamped. Tie cope and drag sections are then removed with the impressions of the patterns upon adjoining faces thereof and are combinedto form the completed mold. The present invention deals more particularly with the means for centering the said cope and drag sections with respect to the match board and with the means for gixing to the cope and drag sections an initial separating movement from the match board.

Referring now to the drawings, and particularly to Fig. 1, the device as there shown, consists of the upper or cope section v8, the lower or drag section 9, and the match board 10 placed between such sections. The

cope and drag section each are as shown of rectangular form and are each formed of two sections 10 and 10 hinged as at 11 in Fig. 7 and the sections are locked together by a suitable locking member 12, as in Fig. 7. The form of the locking member will be clearly understood from Figs. 1 and 2 and consists of a body formed with a U- shaped recess-13 which embraces abutting edges of the sections of the frame. The locking member is pivoted as at 14 and is formed with a suitable finger piece 15. The manner in which thislocking member performs its work is obvious from the drawing. As stated, in casting operations, where split patterns are employed one section of the pattern is fixed to one side of the match board and the other section to the other side and the two sections are placed in alinement. aline and match the impression in the sand of the cope and drag sections it will be nec essary to properly aline the cope and drag sections with respect to each other and with respect to the match board. This is accomplished in the present invention by a simple and effective construction. This centering means, as illustrated, comprises vertically extending posts 16 which are formed integrally or fixedly secured to the plate-like It is obvious that to successfully members 17, (see Fig. 1). There are two of the members and posts employed which are arranged upon opposite sides of the match board and in alinement with one another. Each plate-like member extends inwardly beyond the end of the match board and is cut away as at 18 so that the match board dovetails therewith. Each post 16 is, as shown in the drawings, of triangular formation in cross section and extends above and below the board. The cope section has secured thereto plates 19 arranged upon opposite sides of the section and in alinement I with one another. Depending from each plate is a V shaped end 20 arranged and adapted to embrace the posts 16 as will be seen from Fig. 4:. Plates 21 are attached to the drag section which plates are arranged upon opposite sides of said section and in alinement with one another. These plates are of triangular formation in cross sections as will be seen from Figs. 4t and 5 and these plans have a portion thereof configured to provide inwardly extending ends or fingers 22, which engage the surface of the posts 16 beyond the points of engagement of the end 520 with said post. This will be clearly understood from Fig. 4-. It may be said that the end 20 telescopes with respect to the plate 21. By this arrangement means are provided for centering the cope and drag section with respect to the match board which means are arranged to act independently of one another whereby the centering of the drag section is brought about independently of the centering of the cope section and when the two sections are in position both are centered with respect to the match board. It is obvious that the end 20 affords a means for centering the cope section which is in no wise dependent upon the positioning of the drag section, and that the means for centering the drag section are such as to be in no wise dependent upon the positioning of the means for centering the cope section. Thus in case it is desired to use either section without the other a centeringmeans is provided.

As stated, another object of the invention is to give to the cope and drag sections an initial lifting movement away from the match board which will lift them evenly and without any disorganization of the sand.

Suchfmeans in the construction shown, consists of handle members 23.0n the cope sec 1 tion, and handle members 24 on the drag section. The handle members on eaclrsection are arranged uponopposite sides of the sect on with which they are associated, and are oppositely disposedwith respect to one ani other. The handles are pivoted at each end to cars 25 which ears are secured to or formed mtegral with the said sections, and each handle at each side thereof has a portion 26 extending beyond the pivotal connection and this extending portion of the handle constitutes in effect a lever. When the handles are moved, as shown by dotted lines in Fig. 3, the ends 26 press against the match board and lift or elevate the section away from the match board in an obvious manner. After the initial lifting movement a complete removal of the sections from the match board can be easily effected. The acting ends 26 bear against metal strips 27 which provide a firm surface for the ends to act against and also serve as a binding for the edge of the match board to prevent a warpmg and distortion of the same. These strips overlie the point of juncture of the metallic member 17 with the match board, and serve to prevent disconnection at this point. Thus by these metal strips, together with the members 17 and the dovetailing arrangement of the edges of the match board with said members a firm and strong binding is provided for the match board to prevent a splinting, warping, or twisting of the same.

As shown in Fig. 7, portions 28 of the match board extend beyond the cope and drag sections, and such projecting portions are reinforced by metal rods 29. If desired, a suitable bracket 30 can be attached to such projecting ends to which a vibrator may be attached, if desired. The handle in addition to serving the functions of the lever as hereinafter described, also serves the usual function of hand clasps.

Structural changes are, of course, contemplated provided they are maintained within the scope of the appended claims.
